The lifetime risk is approximately 1.3% for women and 1.8% for men. For regular smokers: 11.2% for women and 14.8% for men. So about 15 to 30 more likely to get lung cancer. Bringing that down to 4x is close to "almost the same".

Might be that I am not reading probabilities correctly, but how do 1.3% -> 11.2% and 1.8% -> 15% become "15 to 30 times more likely"? Sounds like less then ten times?

Good catch, wrote this on the go. The first stat is a study on Canadians, the second is from another source which is global.

You can switch it off, or make it play one of several different ridiculous sounds.

On which vehicles can the humming in reverse gear be switched off? I understand the Tesla (my car) and the BYD (expires car) can not turn that off.

I find "expires" as a swypo for "exwife" somehow fitting.

I grew up in a small town in the mountains in Norway. There is a children's "hospital" there (Geilomo Barnesykehus), where kids come to live because they can't live in the cities. Kids with severe asthma, eczema and some other conditions. It started as far back as the 1930s, still unfortunately a problem so kids have to come live there away from their families.

Better than having to go down a salt mine, I suppose

My anecdote would be the revesre. Living in the country gave me bad hay fever/asthma in the city much less asthma.

You discovered that you have an allergy. Not exactly the same thing.

plus all available evidence suggests that allergies are getting worse due to changes in biodiversity.

the only plants that survive these days are the ones that spam a ton of pollen, so it gets selected for aggressively.

Conservatives flipped on multiple of their policies after Reform's success on local election in 2025 and started to copy Reform UK. Even the Labour shifter right after 2025.

How's Reform UK Ltd. done since then? They've lost 2 by-elections and beaten a bin. Sterling job I guess if you listen to any of their members.

They dropped a few points in pools but for Conservatives they likely will be the main competitor - among Reform UK voters there are much more former Tory voters than former Labour voters.

So you support nuclear power?

This particular brand of confrontational nuclear “advocacy” does not help nuclear. Please consider stopping it.

In what world is simply asking if someone supports nuclear power confrontational?

It really is weird how many people are enthusiastic about stemming climate change but don't support one of the few non-intermittent sources for carbon free energy.

100%, and not just due to no emissions / minimal break dust. The noise reduction is a massive dividend. I used to live in london 10+ years ago, and when I come back I’m stunned by the noise difference, it really is so much quieter especially in central london. EVs everywhere especially replacing the horribly noisy diesel black cabs and buses. Very noticeably different and much more pleasant, and improving all the tim…

Noise reduction benefit is marginal. Most of the noise comes from tires rather than the engine. At 30 km/h tires are louder than the engine, so an EV driving at 50 km/h, which is the typical city speed limit, isn't any quieter than an ICE car.

Noise benefit isn’t marginal. Central London average speed is 7 to 10 mph (11 to 16 km/h) so engine noise is significant. There is lots of idling traffic: traffic lights, taxis at cab ranks, buses at bus stops, everyone in a jam - removal of idle noise is particularly significant.

Is that an aged adjusted statistic? Or is it comparing with the entire gasoline vehicle fleet ?

Why ask things that you can easily look up?

Sea lions don't merely "look things up", they ask you to do it for them.

If you only use 99% it means there are small particles you can't catch. Being faster is meaningless if you can never clean the air. Air purifiers are designed to run 24/7 and all they do is catch particles. Eventually all the particles will be caught. The one I got also detects if there is a lot of particles and will spin faster accordingly.

>If you only use 99% it means there are small particles you can't catch. Air filters don't work like sieves. The smallest particles are easier to block than the mid-sized particles. See: https://en.wikipedia.org/wiki/Mechanical_filter_(respirator) Clean Air Delivery Rate is often specified for specific pollutants. One is smoke, which is mostly small particles.

I am specifically talking about particles in the 0.3 to 1.0 micron range which according to the graph from your link are the most difficult to filter out. Can a 99% filter catch these? My understanding of this is that they cannot.

According to hepacart [1] 99% HEPA filters do not even exist, since HEPA seems to be clearly defined:

> HEPA filter definition, which requires a filtration efficiency of 99.97% for particles as small as 0.3 microns. "HEPA-type" filters may capture larger particles but are not effective against the finer particulates that true HEPA filters excel at removing.

And those of us who don’t can just plug in at home.

Except for the many many people who don't have off street parking.

Very small number in the U.K. outside of big cities and towns. In England 65% have off-road parking outside of London, and most of that 35% will be in cities and towns.

I can’t think of a single house in my sisters village without parking. The village hall also has a carpark with two 7kW chargers.
